Yes, you are right, manually added routes should be imported by kernel
protocol (while 'native' device routes that are created by kernel
could be imported using direct protocol).

There is one issue related to routes without gateway, see this thread:

http://www.mail-archive.com/bird-users@atrey.karlin.mff.cuni.cz/msg01039.html

In short, there are two ways to fix it. Either use attached patch to BIRD
source and rebuild, or create these routes with another 'protocol source'.
I don't know whether 'protocol source' could be changed when route is
added using 'route' command, but for 'ip' command you can use

ip route add 172.16.100.100/32 dev eth0 proto static

instead of just

ip route add 172.16.100.100/32 dev eth0
